Ah. This could be a problem. Now, when you say "many TCP connections
from one host are scheduled to different real servers" I assume that
this means something like several separate web page requests, or several
telnet sessions. So if a server opens a connection to VIP:PORT, until
this port is closed, all the packets would go to the one realserver.
Okay, that makes sense.
Hmmm. May have to go back to the drawing board on this one.

Non Disclosure Agreement. It means I can't tell you enough for you to
help me, but if I say anything at all I get in trouble. :-)

Based one the info I have at present, yes it is.

Sigh. I was beginning to get that impression myself. Back to the

Now that is a good bit of news...
Thanks,
